Battle of Tasil

The Battle of Tasil (21 March 2016) was an incident during the inter-rebel conflict of the Syrian Civil War. The Yarmouk Martyrs Brigade, affiliated with the Islamic State, attacked the town of Tasil in Daraa Governorate and seized it from their al-Nusra Front rivals in a minor victory.

History
The Yarmouk Martyrs Brigade component of the Islamic State had a rivalry with the al-Nusra Front for a few years, having joined ISIS against both the Syrian government and the Syrian Opposition. On 15 November 2015, al-Nusra assassinated their leader Abu Ali al-Baridi, and the two groups engaged in clashes in southern Syria in Daraa Governorate and nearby areas. On 21 March 2016, the Yarmouk Martyrs Brigade launched an assault on the town of Tasil in Daraa, killing al-Nusra leader Abu Salah and enforcing ISIS' rule in the town.
